INCANDESCENT ELEoTmo-LAMP FIXTURE. 7,

Application filed December 4, 1923. Serial No. 678,514.

To all whom it may concern:

Be it known that I, CARL H. BISSELL, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Incandescent Electric-Lamp Fixture, of which the following is a specification.

This invention has for its object a particularly simple and efiicient incandescent electric lamp fixture, comprising a housing and guard construction for incandescent electric lamps having large bulbs, by which construction the large lamp is readily assembled in a guard carried by a comparatively small box in an electric conduit system, and readily removed and replaced.

This invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawing which is an elevation partly broken away of a lamp and a lamp housing and guard embodying my invention.

This lamp housing and guard, is of the type used l in electric conduit systems, in which is connected a fixture or box for the outlet of wires to the lamp and for supporting the lamp and guard therefor.

These boxes are limited in size and the guards for the lamps supported in the socket in such boxes are rigidly connected directly to the box. As the boxes are limited in size the passages of the guards or the bases of such guards connected directly to the boxes through which passages the lamps project into the guard are also correspondingly limited in size, and the size ofthe lamp limited to the size of such passage. Heretofore, the lamp has been'placed in the socket when the guard is removed, and thereafter the guard passed over the lamp and secured to the box or body. Hence the size of the lamp inserted in the socket has been limited to the size of the passage at the topof the guard, for the reason that the lamp must pass through the hole or passage in the-base portion of the guard.

By my invention the lamp bulb can be attached and removed regardless of the size of the opening in the base portion of the guard, which base portion is connected directly to the box or body.

1 designates the box or body which is cupshaped in general form, and which is internally threaded at its outer and lower large end, and provided with threaded nipple 2,

at its upper end for connection with electric conduit.

3 designates the lame socket mounted in and projecting through the open side thereof. 4 is the base portion of a guard, which base portion has an upwardly extending flange 5 threading in the lower end of the body 1. Owing to the limitations in the size of t e box 1, the opening 6 is confined by the flange 5 is also necessarily limited. Heretofore the lamps have been attached to the socket and then the guard passed over the lamp bulb and attached to the body or box 1.

7 designates the lamp mounted in the socket 3 and having a bulb of greater diameter than the opening 6, so that, it cannot be passed'through such opening or rather the guard cannot be passed over the lamp bulb.

8 is the cage of the guard which cage may be of any suitable construction, it having the upright rods 9 which are secured at their upper ends to a ring 10, secured to the base 4 as by screws 11, this cage 8 has a removable lower section 12 hinged at 18 to the up per section and normally held in position by a screw 14, arranged diametrically opposite thehinge 13. As here shown the upper section of the cage is formed with a flat ring 15 at its lower edge, andthe lower section is formed with a flat ring 16 at its upper edge, and these two rings meet each other and are hinged together at 13 and the screw 14: extends through the flanges 15, 16.

The globe 17 is mounted within the cage,

' this globe resting at its lower end on a yielding seat as a coil spring 18 carried in the lower part of the lower section 12 of the cage, such globe thrusting at its upper end against a gasket 19 located between the annular lower face of the base 4 and the rin the body or box 1, in any suitable manner,

its normal position and the section 12 is closed and fastened.

What I claim is:

In an incandescent electric lamp fixture, comprising a cup-shaped body having an opening in its larger end, a lamp socket mounted in the body, and exposed through the opening, a lamp guard, comprising a base having a threaded neck, threading in the open side of the body, the base flaring outwardly from the neck, a cage carried by the base and secured to the outer margin thereof, the cage having a removable lower portion, a globe thrusting against the outer end face of the base, and a spring carried by the removable portion of the cage and thrusting against the lower end of the globe.

In testimony whereof, I have hereunto, signed my name, at Syracuse, in the county of Onondaga, and in the State of New York, 20

this 13th day of November, 1923.
